HABSAGHUS MANUFACTURE OF CORD FABRIC. Application filed Kay 15, 1822. Serial No. 580,018. To all whom it may concern: various forms of textile machinery.

This construction avoids the nscesls ty Figs. 7 and 8. In these figures the roll has of having a comb of extreme fineness, w

been shown connected to the lower roll of atdds cost and complexity and also provides no the calender, which, by reason of its being space which permits of the passage of knots fired to the other calender rolls, will drive in the cords. It is desirable to operate the roll 32 at a peripheral speed having an calender continuously until the desired amount of'cord fabric has been produced. If it is necessary to stop the calender and restring all the cords after the tubes 12 have become exhausted, much time will be con-. sumed and, if the rubber stock is left on the calender during the restringing period, the rubber will lose its proper condition of plasticity and much scrap will result. By so arranging the comb that am le space is provided for knots to travel t rough, the tubes of cord may be spliced and replaced while the calender is operatin a In order not to have all the ots come at one place in the com osite sheet, and to facilitate the work of e operator in splicing the large number of tubes mountedon the creel, I preferably arm the tubes initially so that they have varying le 8, of cord on the several tubes, convenient in regular progression from one extreme o the creel to the other. This has been indicated diagrammatically in Fig. 1 by-the difierence m diameters of the various tubes. The tubes in the horizontal rows are indicated as being of substantially uniform size, but it will be understood that all the tubes are preferably arranged in a re ar progression. The operator can with is arrangementjwork from one section of the creel to the other, replaeing with full tubesthe ones that become empty, and tying from an emptie tube the leading end of the cord from a full tube. As the full tubes are supplied with substantially uniform lengths of cord wound thereon the order in which the tubes become empty will remain the same after the initial setting-up, and thecreel requires no attention other than the regressive replacement of the tubes as t ey run out.

Another feature of my invention by which I insure regularity in the operation of the apparatus is illustrated in Fig. 10. The cord is supplied wound in so-called tubes 12 on a core 70, the cord being wound helically back gniildforth on a core in a manner as to u up a tu containing av great length of cord. As the cord is wi drawn from the tube as the latter is in use on the creel, the cord. is at intervals drawn ofl from points 71 at the edge of the tube. Sometimes the cord at this ,point will slip down the endof the tube particularly if the tube has been subjected to rough handling before mounting in the creel, with consequent unevenness of feed and inequalitguef tension, even resulting at times inbin g and breaking1 of the cord. To avoid this difliculty wi out interferin with therubber coatin o ration, I pre erably coat the ends 72 o t e tube of cords with an ad: hesive sufiiciently firm to prevent the cords slipping over the end of thetube and-yet permitting their being drawn of as afiect the adhesion to the cords of the later applied rubber and may conveniently be composed of ru ber cement. If this cement is applied to the ends of the tubes after the latter have been wound it will protect them in handling and prevent breakage of cords in oferating the calender. l

I a wide range of adjustment of the spacing of the cords is desired, a second ad ust-, ab e comb Flimsy be placed adjacent guide roll 21. This may be of the same type as comb 80, or as indicated diagrammatically in Fig. 1, :0 the so-called saw-tooth type of comb in which the pins are mounted in a zig-zag line along the links of 0. Ian -tongs, lag the stretching or contracting 0 which e spacing may be adjusted. vThis t of comb is alsoknown in various textilev evices, and needs no extended discussion here .as to the details of its construction. The provision of this second comb breaks up the variation in spacing between guide 14 and the calender into two sections, and gives more accurate control than in case a single comb only were used. to the last end of the cord The composite sheet 67 resultin from the first coating operation is delive from roll 66 to a wind-up drum 80, referably power driven as is customary wit calender windup devices, and mounted so that it will not haveany endwise. motion. A liner 81 is fed under tension from a s 001 82 between the .convolutions of the cor fabric sheet on the drum so as to prevent the adjacent turns sticking together. After all the material has been run that is desired or that can conveniently be mounted on drum 80, the sheet is severed, and the cords tied back as previously described. The calender is now made ready to deliver stock of the gauge and mhty desired for the second coat. For second coating 0 ration, thepartially finished sheet 67 is ed from drum 80 under the bottom calender roll 27 around a guide roll 83, and between the two bottom calender rolls, where it is p against a rubber sheet formed by the upper air of rolls. The finishedsheet indicated y 84 in Fig. 1, is led around roll 66 and delivered to any suitable windup device. The liner 81 is d this operation rerolled upon roll 82, whic may be actuated by an suitable wind-up device.
